Governor Rick Snyder says emergency actions are necessary to address low water levels in the Great Lakes.

The lakes are at their lowest levels in decades.

Snyder says that could be a big threat to Michigan’s harbors.

“There’s going to be a need to do some, what I would describe as emergency dredging, to make sure we keep it open for commerce, for tourism, for many other issues. And that’s something we need to be discussing,” Snyder said.

Snyder called for more than a $1 billion increase in state infrastructure spending during his State of the State speech this month.

He says improvements to harbors and canals should be part of that plan.

The governor says he’ll give more details about his emergency plan for the Great Lakes during his budget presentation next week.
